It brings us a lot of convenience and makes our life much easier and more colorful. We can do almost everything online. For middle school students, the Internet is a good helper for study. We can search for useful information, take online courses, read news from safe websites and learn new skills every day. It helps us open our eyes and know more about the world. However, the Internet also has its disadvantages and risks. If we use it in a wrong way, it will be bad for us. Some students spend too much time playing online games, watching videos or chatting on social media. Too much screen time is harmful to their eyes, health and schoolwork. They may feel tired easily and can’t listen to teachers carefully in class. What’s worse, some bad people use the Internet to do bad things. They may steal our personal information, send harmful messages or do online bullying. Some students even meet strangers online without telling their parents, which is very dangerous. So it is important for us to use the Internet wisely and properly. We should make a clear daily plan for our online time and follow it strictly. We must protect our personal information and never share our password, address, phone number or ID number with strangers online. Before we click a link, we should double-check it to make sure it is safe. If we get bad or unfriendly messages, we should not reply. We can take a picture as a record and tell our parents or teachers at once. The Internet is a wonderful tool. It is not good or bad itself. It depends on how we use it. If we use it correctly, it can help us a lot. If we misuse it, we will get into trouble. Let’s learn to control ourselves and make good use of the Internet. 31.

We can talk to friends or family far away, send messages and have video chats on social media at any time. We can keep in touch with each other easily no matter where we are. Secondly, mobile payment is very popular. We can buy things, pay bills and book tickets without cash, which saves a lot of time. Thirdly, we can use mobile phones to search for information, listen to English, watch educational videos and learn new things anytime and anywhere. But every coin has two sides. Mobile phones also bring us some problems. If we use them too much, we will have many health problems, such as eye tiredness, headaches and neck pain. Many students don’t get enough sleep because they use mobile phones before going to bed. What’s more, some students spend too much time on mobile phones instead of doing sports or studying. They even use them in class, which influences their study a lot. Some students are also easily influenced by bad information online. To solve these problems, we should use mobile phones in a right way. We should limit our screen time and take a break every 30 minutes. We should use them mainly for study and useful communication, not for playing games all the time. We should also stay away from bad websites and information. Parents and teachers can help us make a good plan for using mobile phones. In this way, we can enjoy the advantages of mobile phones and keep healthy and happy. 36.

First, we should choose safe websites and apps. We should stay away from the websites with bad pictures, videos or information. They are bad for our mind and growth. Second, we must protect our personal information. We should never tell strangers our real name, address, phone number, school name or password. We should not put our personal photos or information on social media easily. Third, we should be careful when we make friends online. Not everyone online is friendly. Some bad people may use false information to cheat us. We should not meet online friends alone without telling our parents. Fourth, we should not click strange or doubtful links. These links may bring viruses to our phones or computers, or lead us to bad websites. Fifth, if we meet online bullying or get bad messages, we should keep calm. Do not reply or fight with them. We can take a screenshot to keep the record and ask our parents or teachers for help in time. We can also report it to the Internet police if necessary. At last, we should control our online time.
